9b97a73ded Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

f82f4490b1 MC: Sketch initial MCAsmLayout class, which encapsulates the current layout of an assembly file. The MCAsmLayout is also available for use by MCExpr::EvaluateAs{Absolute,Relocatable}, to allow target specific hooks and "absolutizing" of symbols.

functionality change other than unbreaking my previous patch.
